Network node processors (NNPs), which can execute application programs and can cooperate with each other via high-speed LANs, have become essential components for distributed online systems. DCNP is a data communication management system for NNP. DCNP provides unified communication interfaces and high-performance and highly reliable communication services. An addressing technique which unifies program interfaces for node-to-terminal communications and internode communications is presented. Socket interface extensions for improving performance and techniques for highly reliable internode multicast communications on multiple LANs are also presented. DCNP has been implemented with a Unix kernel on fault-tolerant minicomputers and is operating in online systems
